Step-by-step explanation:
A rational number can be written as a ratio a/b, where a & b are integers & b \neq 0. Rational numbers are terminating or repeating. The radical sign means "the positive square root of."
Example:
√144 = "the square root of 144" but indicates the positive square root of 144, which is 12
Hope this helps!!! :)
Answer:
Rational equations or expressions (think rational numbers) are any expression which is in fraction form and where the denominator is not equal to zero. Like: [tex]\frac{2}{x} ,\frac{3}{5}[/tex] etc.
Radical expressions are those expressions that contain radicals (square, cube, fourth roots). Like 4 and -4 are the square roots of 16. A square root is written with a radical symbol √ and the number inside the radical symbol is called the radicand.
